Bug#1067646: llvm-toolchain-17: please enable m68k build

[Thorsten Glaser]

Source: llvm-toolchain-17
Version: 1:17.0.6-9
Severity: important
X-Debbugs-Cc: tg at mirbsd.de, debian-68k at lists.debian.org

Attempts to build llvm-toolchain-15 (needed for qt6) and 17 (which
is apparently what everyone should switch to, but 16 might also need
it) fail at configure stage:

  The target `M68k' is experimental and must be passed via
  LLVM_EXPERIMENTAL_TARGETS_TO_BUILD.

Please do so ;-) I guess.
